THREAD-GUIDING AND TENSlON-REGULATING DEVICE FOR LOOlVl-SHUTTLES.

SPECIFICATION forming part of Letters Patent No. 363,005, dated May 1'7, 1887.

Application tiled June 30, 1830. Serial No. 206,693. (No model.)

To all whom, it may concern.-

Be it known that I, J AMES 0. SERGESON, a citizen of the United States, residing in the city and county of Philadelphia, State ofPenir sylvania, have invented a new and useful Im provement in Thread-Guiding and Tension- Regulating Devices for Loom-Shuttles, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 represents a side elevation of a portion of a loonrshuttle embodying my invention. Fig. 2 represents a top or plan view thereof. Fig. 3 represents a longitudinal section thereof in line a: .r, Fig. 2. Fig. 4. repre sents a transverse section in line'y y, Fig. 2. Fig. 5 represents a side elevation of a detached portion. Fig. 6 represents a vertical section thereof. Figure 7 represents a side elevation of a portion of a modification. Fig. 8 represents a section in line n, Fig. 7.

Similar letters of reference indicate corre sponding parts in the several figures.

My invention relates to improvements in shuttles for looms; and it consists in providing the same with thread-guiding and tensionadjusting devices, as hereinafter described and claimed, whereby the yarn or thread, when doubled or snarled as it runs from the cop or bobbin, is prevented from fouling or tangling, and the tension of the thread while being fed to the loom is properly regulated or adjusted.

Referring to the drawings, A represents the body of a loom-shuttle, and 13 represents an eye or slotted plate, which is fitted in an opening in the side of the body A, one of the walls of the slot of'said eye being longer or higher than the other wall, and set back so that the eye is in communication with the interior of the body of the shuttle, so that the yarn from the cop or bobbin may be passed out through said eye.

Rising from within the body A, forward of the eye 13, is a conical post, U, at the top of which is a horizontally-arranged flange, I), having a dowmvard-projccting lip, D, it being noticed that a recess, a, and channel b exist, respectively, between the post and flange and adjacent portions of the shuttle-body, said flange appearing at the top of the shuttle-body, substantially in the manner shown in the Letistiug'bctween the point of the screw and side of the post for the passage of yarn. (Jircunr scribing the post at or about the point of the screw ll is a flange, K, which is cut away, leaving a passage, 0, inside of the point of the screw.

The operation is as follows: The yarn from the cop or bobbin is directed by hand into the channel Z) and run around the same, whereby it passes under the flange D, the lip D thereof serving to keep the thread in place, and then around the post 0, and rides down the guard G and drops from the bottom of the same against the outer face of the conical point of the screw H and rides thereon until it clears said point, when it rises through the passage 0 of the post and passes behind the point of the screw, and remains in contact therewith. The yarn continues around the post and comes in contact with the wall 11 of the eye B, and is deflected by the same into the slot or opening ofthc eye, thus threading the eye where it may be drawn out by the lingers or a hook, and thus run into the eye, its proper position when the shuttle is in use. Should there be too great tension on the thrcad,thc screw H is rotated, so as to be raised, whereby the conical point presses to less extent against the yarn, and should the tension be again insufficient the screw is rotated so as to be lowered, and thus the conical point increases its pressure on the yarn.

In Figs. 7 and S the point of the screw is cut away in the direction of its length, or shouldered, so as to make said point wider in one direction than the other, the yarn being in contact with the side edge of the shoulder of the screw, so that when the screw is rotated it presses against the yarn to greater or less extent, and thus adjusts the tension thereof.

ICO

When the yarn runs off from the cop or bobbin, it often doubles,twists, or snarls, in which condition it would strike the top of the flange on the side facing the cop or bobbin and be directed in the doubled or snarled condition into the passage 0 and foul or tangle around the post 0, were it not prevented by the recess E, against which the doubled yarn first strikes, and is thereby prevented from immediately entering the passage 0, and is straightened out, or may be seen and relieved.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A shuttle having a conical post with a top flange, the latter with a recess in its side and separate from the body of the shuttle, a

depending guard, and a screw or pin passing through the flange, all substantially as and for the purpose set forth.

2. A shuttle provided with a conical post in a chamber within the same, the said post having a top flange with a recess in its side, and a lower flange near its base, with a recess in its side, and a pointed pin passing through said top flangeand having its point near said recess in the said lower flange, all substantially as and for the purpose set forth.

3. A shuttle having the eye B,with bent part B, the conical post (3, with recess J, the guard G,and top flange, D, the pointed pin or screw H, and the circumscribed flange K on the post 0, all substantially as and for the purpose set forth.
